Background

Varicose veins are commonly seen in peripheral vascular diseases, usually marked by varicose veins in the greater or lesser saphenous vein of the lower limb, which are characterized by earthworm-like tortuosity in the superficial veins of the lower limb. These venous valves are often pre-stressed to fail and, instead of returning blood properly, may cause shoe reflux or local dead circulation, causing tissue necrosis at the site of the blood supply. In the prior art, the method for treating varicose vein is to ligate the root of the great saphenous vein at a high position and carry out the stripping operation on the diseased great saphenous vein and the varicose branch vein, and a varicose vein stripping appliance is needed. The traditional varicosity stripping appliance comprises a guide wire and a stripping head arranged on the guide wire, when in use, a vein vessel and the stripping head need to be fixed by a surgical line, and then the vein vessel can be pulled and stripped by pulling the guide wire.

in this embodiment, as shown in fig. 5 and 6, a reinforcing groove 23 is disposed on the peeling head 20 and located on the opposite side of the open side groove 22, the length of the reinforcing groove 23 is smaller than that of the open side groove 22, a secondary closed board clamping groove 12 is disposed on the side of the reinforcing groove 23 corresponding to the closed board clamping groove 1, a secondary closed board receiving groove 13 is disposed on the side of the reinforcing groove 23 corresponding to the closed board clamping groove 2, the secondary closed board receiving groove 13 and its internal structure are identical to the closed board receiving groove 1 and its internal structure, and the secondary closed board clamping groove 12 and the closed board clamping groove 2 have the same structure; one end of the reinforcing groove 23 facing the open side groove 22 is communicated with the central hole 21, and one end of the reinforcing groove 23 facing away from the open side groove 22 is positioned between the outer side wall of the secondary closed board clamping groove 12 and the surface of the side stripping head 20. The arrangement is such that the closing plate 3 and the secondary closing plate are always symmetrical about the centre point of the central hole 21, so that when clamping and fixing the guide wire 10 sheathed with a venous blood vessel, the direction of the force of the closing plate 3 and the secondary closing plate on the guide wire 10 is symmetrical about the centre point of the central hole 21.

The rest is the same as example 1.

The above-described application process of the varicose vein stripper is different from that of example 1 in that:

when the closing plate 3 exerts a compressing effect on one side of the guide wire 10 sleeved with the vein, the closing plate 3 is provided with an auxiliary closing plate on the opposite side of the center hole 21 to exert the compressing effect, the action mechanism of the auxiliary closing plate is consistent with that of the closing plate 3, and the action direction of the auxiliary closing plate is symmetrical to that of the closing plate 3 about the center point of the center hole 21, so that the guide wire 10 sleeved with the vein can be accurately positioned at the center position of the center hole 21, the stripping head 20 is ensured to be coaxially fixed with the vein and the guide wire 10, and the peripheral side of the stripping head 20 can be ensured to uniformly act on the peripheral side of the vein in the drawing process of the guide wire 10. As can be seen from fig. 7 and 8, when the device is applied to venous vessels with different thicknesses, the curved plate can still tightly press the venous vessel with the guide wire 10 therein against the side wall of the central hole 21 opposite to the open side groove 22 under the action of the torsion spring 7, so that the device has strong applicability and ensures the fixing and limiting effect of the stripping head 20 on the venous vessel and the guide wire 10.

The rest is the same as example 1.

As can be seen from the above, the utility model has simple operation, is suitable for the situation that the vein thickness is different for different individuals, and can ensure the fixed spacing effect of the stripping head on the vein and the guide wire.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
